How I got DOOM running on Hytale's world map?

I'm using MochaDoom, which is a pure Java port of the original DOOM engine. The trick is running it "headless" - meaning no window, just the game logic running on the server. Every frame, I grab the raw pixel buffer from DOOM and stream it to players through Hytale's world map system (the M key map). Delta compression keeps bandwidth low by only sending pixels that actually changed between frames.

The input problem and how I solved it:

The challenge is that when players have the map open, they can't use normal mouse/keyboard. So I had to get creative with how inputs are detected.

For movement, I track the player's position on the server. When they try to walk with WASD, I detect which direction they're moving and translate that into DOOM's arrow keys. The player doesn't actually move in the world - I teleport them back to their original spot - but DOOM receives the input as if they pressed the arrow keys.

For shooting, I detect when the player jumps. Any upward Y movement triggers a weapon fire in DOOM.

For everything else (weapon switching, opening doors, menus), I use hotbar slot changes. Pressing 1-4 selects weapons, 5 fires, 6 opens doors, 7 is enter, 8 is escape. This works because hotbar keys still function while the map is open.

Thus, The Game is Running Entirely Server-Side. And it's Updating at 35 FPS at a resolution of 320x200
